yum is /usr/bin/yum
To use Certbot on this operating system, packages from the SCL repository need to be installed.
Enable the SCL repository and try running Certbot again.

and than i use command: 
#yum install centos-release-scl

CentOS 6 is end-of-life and all of its software repositories have been taken offline. As such, Certbot no longer supports it.

You could try another ACME client.  
Like: `acme-sh`

It shouldn't have come as a surprise. I recommend to invest more time and effort into learning about deprecation of software and keep your software up to date.
